Fig. 3 is a top plan view of thefsame' The advantages of theinventionare best i ,7 realized 1n a structure comprising, as shown,

' a magazine communicating at a right angle,

or approximately so, with an eyelet guide these elements being mountedat one side of and operated by an eyelet setting plunger, adapted toimpart thereto a compound swinging and rocking motion, as hereinafterdescribed. Referring to the several the numeral 11 therein denotes abase or foot plate, from which extends an arm 12,

carrying a housing 13. These various'elements may be hollow, as shown.Holes 14 are-provided in the base to receive screws for holding it to aprimary support, and a plate 15, covering the upper end ofthe housing issimilarly fastened thereto, as by screws 16'. H g

x The said housing 13 is formed with a guide) 18, for a plunger 19 andwith bearings 20 20"., for a spindle 21. An operative connection iseffected between the plunger and the spindle, the same being shown inthe present jexemplification of the invention as "consisting of arack-22,-carried by the said plunger and engaged by a pinion 23,fizged-- to the said spindle. To the outer end of the latter is secureda crank ,arm 24, carrying at its free extremity a stud 2 5', on which ismounteda knob'26, for convenience in' manipulation. Although this viewsaforesaid,

ferred one, it should nevertheless be under? stood that any othersuitable combination or end of the plunger, and the barrelcoi'itain-111g the-spring 1s closed-at, the top byaneans construction is hererepresented as the prearrangement of parts may be employed instead.

disposed in direct alinement therewith, is a prercmg stud 3'4 extendingupwardly from an anvil'plug 35, set in the base 11, centrally beneaththe said plunger. 1

The last mentioned elements may be used .alone :to punch or pierce ,alayer otpaper, fabric, or llke material placed upon or over the stud34:. As, will be noticed-by reference .to Fig. 4,'thisstud is-slightlydished on top,

The mode of procedure just outlined con- .forms-in substance with thepractice 'genen ally followed in this art.

A gage 40 1s provided, to assistfin correctl-y locating the material; tobe .eyeleted witha relation to the .plniclnfor instance, in. squaring"sheets .of paper. that are to be -bound together and insuring that theeyelets-be inserted uniformly in parallelism withone edge thereof at.any specified disiscarried :bya rod 4 1. which may be. adjustably heldinposltion by' means of a screw 42, in the lowerpart of. thearin ,12.

Suspended atone side of and offset from the plunger v19, is a, guideor-chute 50,-for the eyelets Th1sgu1de inch des. shallow grooves 51,located internally on opposite sides thereof in position to receive theflange of each eyelet as it slides between them, and" ab ito fadmitl ofthisarrangement. 1

An arm 55 extends inwardly from one "side of the said chute, below the cent er'of is provided at its inner end with a hub 56 having a hole 57through which is passed-a screw 58, received] at its oppositeends inears 59%, 59" projecting. outwardly'from the rear of the housin Thescrew- 558. thus affords a pivotal means of suspension forthe arm andthe chute 50 connected therewith. Moreover, the ends of the hub arerounded. as shown in Fig. 1, and the hole therein is made of somewhatlarger diameterthan the screw158, as seen in'Fig. 2,to

' result that thechuteis permittedconsiderable freedom of movement.especially the upper end thereof. which not only isenabled- -to swing ina vertical;plane,'but 1 also has a \vabbling or rocking motion sidewise.These combined swinging and rocking movements are particularly -advanta,;eous in insuring thev proper descent 'of the eyelets,which-aredeposited in a magaZine GO, attached to and communicating with'the, upper endof the -cl1ute,.preferably at a right. angle, as shown. IThe. action is such'as to preclude,-.the bridgmagazine'. n

Referring further to the arm 5 5,:it will be noted that the same isprovided at its upper edge with a rearwardly pointedspur 64 adopted tobeengaged by a detent,whicl r as shown may be in the nature of a latch'65, pivotall'y suspended from a"; screw or .pin

In order-to "prevent the eyelets that re- Zin ain" in thechutefffrom'sliding out prematurely therefrom, 'a retainer isprovlded,

The said spring 74, is contained within a recess78, formed in the heel portion 7 30f the ehute50.

The hereinbefore mentioned magazine 60 comprises a receptacle ofsubstantially pyriform outline, as viewed in plan, one side thereofdrawn to a taper and fastened to a backing piece 82. The latterconstitutes an attachment to the chute 50, to which it is held from therear by screws 83. Prefer ably, this backing piece is composed of threesuccession: First, an apertured plate 84 is made to extend transverselyacross the interior of the magazine, presenting therein a plurality ofopenings 85, the lowerportions whereof are widened as at 8 6, Fig. 4, toaccommodate the heads of theeyelets, when the latter are lying withtheir tubular shank portions uppermost on the bottom 87 of thereceptacle. Secondly, a guide plate 88 is setabove the bottom 87,-at asufiicient distance therefrom rear of the apertured plate aforesaidto'provide a-clear space for the eyelets to'slide under the guide,without permitting them, however, to 'tip or turn over ontheir' sidesandbecome stuck between the opposed surfaces 87 and 88. A passage 89 isformed between the latter-. namedwsurfaces with its sides converging inconformity with the tapering rear portion of the magazine andterminating in an aperture 90, which leads out of the backing 81 atasubstantially right angle into Owing to the and there make a quickquarter turn so jas 12 to drop from .the magazineainto the chute, wherethe head of the eyelets becomes at once engaged by thelateral grooves51;, the shank following thecentral channel Thirdly,

an inclined partition 91 isprovided in the magazine, the same extending.froni thetop of the backing piece 82 down to the upper edge of theapertured plate 84. The oilice of this-inclined" partitionis toutilizeath e force-of agitation to which the eyelets are subjectedthrough the compoundmovement llnparted to the chute and 1nagaz1ne, as'they slide up and down the partition 91 with such other evelets as mayhave alread" "shows these'elements in varying positions,

"as the wabbling or rocking motion brings them opposite thesolidportions of the said plate,- and then'ext downward oscillation'of theydrop in succession", through the opening 90.

For the purpose of enabling the operator of the device to detect anddislodge imperfeet eyelets,.-if the like are perchai'ice deposited'inthe magazine and happen to become stuck in the chute or in theinterconnecting aperture 90, two'or more slots, as 92 and 93, are formedboth in the front'and rear walls of the chute, for instance, oppositethe' said aperture, and-at some point Figshl and} a The magazine 60 isprovided on topjwith a hinged lid 94:, adapted to'be snapped over asuitable fastening button, as 95. The lid, it is understood, preventsthe eyelets from being spilled out while he magazine-is agitated. f

Theaction of "the plunger 19 and of its ii'npa'ling pin 30 upon thedelivery end of the chute 50 is clearly illustrated in :Fig. 6,-whichrespectiv 'ely indicated by the letters A, B, C, and D. As representedat A, the "plunger 19 upon being drivei'rd'ownagainst the lower end ofthe chute causes it to vrece'de therefrom, and at the same time the pin30 sliding out of the oblique slot 69 imparts a lateral movement to thechute, which'produces I he Wabbling hereinbefore setforth, due to thepeculiar pivot l connection vith'the' plunger housing, that is,the meansof suspension. As soon as the pin 30 has come out of the slot 69, andthe plunger descends farther past the enclof the chute 50, then thelatter shifts to the position indicated at B, which inthe coverplate 53,adjacent to the arm 55,
